Glyphosate (GLY) is the most common and widespread herbicide applied to prevent unwanted weeds. However, its detection with conventional analytical methods is a hard task. In this regard, this contribution proposes an original impedimetric electronic tongue (IET) based upon CeO2-graphene oxide chemical sensors and principal component analysis for easier detection of GLY. This IET was capable of detecting GLY within a linear range of concentrations, 110 to 290 nmol/L (R-2 = 0.99), showing a limit of detection of 30 nmol/L, which is far below that established by international safety regulations. This was made possible even in the presence of potential interferents, namely aminomethyl phosphonic acid and N-nitroso glyphosate. The IET per-formed identically to quantitative 1H NMR at 95 % confident level. Once it does not rely on redox reactions or previous derivatization, this IET is a simpler alternative to detect and monitor GLY and its interferents in aqueous media.
